Answer:
Magnesium (Mg) is 1, Nitrogen is 2, and Oxygen is 6
Explanation:
the reason Nitrogen is 2 and Oxygen is 6, is because the number after the parenthesis means you have multiple whatever is inside the parenthesis by that number.
Answer:
B.
General Formulas and Concepts:
<u>Chemistry - Organic</u>
- Hydrocarbons
- Bond-Line Notation: Each "arrow" point represents a carbon and the lines represent a bond between the carbons. Hydrogens are assumed added when drawing the molecular formulas
Explanation:
We are given C₈H₁₈. We need a Bond-Line notation where there are 8 "arrow" points (which represent Carbon). We can disregard the Hydrogens as they are assumed to take the rest of the bonds.
Only option B has a value of 8 carbons, represented by the "arrow" points. Therefore, it is the correct answer.
Answer:
B. They all have molecules in motion.
Explanation:
All substances have molecules in motion, this is because all substances have an average kinetic energy (temperature) of over 0 K.
Answer:
Ionic bond
Explanation:
The magnesium atom gives up 2 electrons to form a magnesium ion, Mg2+ . The two electrons are transferred to fluorine atoms to form two fluoride ions, F–.
